Hi Zyxel Support Team,I am currently using a Zyxel NR5307 5G router (photo attached)

. The device is currently running the customized carrier firmware version V1.00(ACOM.0)b1 (Hiper ISP branch).Because it is running this specific provider build, the built-in Over-the-Air (FOTA) upgrade tool states that no newer firmware is available. However, I want to update the device to secure it against recent security vulnerabilities (such as CVE-2024-5412) and stabilize the connection.I am looking to transition this router over to the generic/global baseline firmware track (such as 1.00(ACJT.0)B6 or the latest available ACJT release).

Could you please provide:

1. The standard .bin file for the latest global firmware release for the NR5307.
2. Any necessary transition/migration firmware file required to bypass the ACOM carrier lock if a direct flash isn't supported by the GUI.

Thank you for your time and assistance!

Hi everyone,I am facing the exact same issue with my Zyxel NR5307. I purchased this device second-hand, and it is currently locked to a foreign carrier (Odido / former T-Mobile Netherlands). Because of this carrier-customized firmware, I am completely unable to configure national APN parameters or use any Italian SIM cards, as the network connection is entirely restricted. I would like to kindly request the official generic/global baseline firmware track file (such as the ACJT release) and any necessary transition path firmware to bypass the current provider lock through the GUI.Here are my device details:

Model: Zyxel NR5307

Current Firmware Version: QuectelT830R03A01_xx.001.xx.001 / V1.00(ACOM.0)b1

Thank you so much in advance for your support!Best regards,

Franco
